HMI Technologies’ Vision SID Sign has taken the strengths from the previous unit and built on them.

Changes include larger more visible character heights, increased energy conservation and dual colour display (Amber & White). The sign uses radar technology to display the speed of approaching cars back to the driver. If they are exceeding the pre-set speed limit, the SID flashes ‘SLOW DOWN’. This interactive speed control method has proved highly effective at changing driver behaviour.

The signs have also proven effective at increasing driver awareness of speed and thus helping to reduce the number exceeding the speed limit. The SID can also be used in combination with other devices such as a variable message sign or arrow board to create a speed control system.

The ability to record traffic data such as speed, time and date allow the units to be highly useful in the collection of traffic information. Mobile options mounted on a trailer add a further dimension of flexibility.
